چکیده
Abstract The first and second law analysis was performed on a Single Cylinder, Multivalve, Electronic Fuel Injection, high-speed motor fuelled engine with Gasoline Hydrogen to assess energetic exegetic performance. evaluated from 3000 rpm 6000 both fuels. All tests are conducted at Wide Open Throttle conditions. gasoline combustion stoichiometric, hydrogen lean burn. most extreme energy exergy efficiency observed 39.06% 36.58% separately. fuel 36.8 % 34.6 recorded the same speed of rpm. highest performance is due high flame speed, higher temperature. This shows that converts chemical yield more power than gasoline. coolant additionally fuel. lowest outcomes checked investigation each found heat release rate hydrogen, trailed by greatest destruction 48.57 kW followed minimal hydrogen. entropy 49.45 W/K for 22.22 hydrogenengines individually.
